Technical Service Bulletins

This article supersedes TSB 06-15-1 to update the service labor operations.

ISSUE:

Some 2005-2007 F-Super Duty vehicles may exhibit steering wheel oscillation (back and forth motion), immediately following front or rear wheel impacts (i.e. pavement joints, frost heaves, rough roads, etc.). Steering wheel motion is typically in the range of ± 5 degrees, and typically dampens out in fewer than five oscillations. This condition occurs mostly on 4X4 vehicles, and is more evident on trucks equipped with a gas engine.

ACTION:

Refer to the following Service Procedure to minimize the steering wheel oscillations on impacts, however, there may be some remaining minor oscillation which would be considered normal.

SERVICE PROCEDURE SUMMARY

Set tire pressure and road test vehicle to evaluate vehicle before proceeding with further repairs. If issue is resolved, do not proceed with the rest of this TSB

Wipe down and inspect the steering damper. Turn the steering wheel from lock to lock several times to cycle the steering damper and inspect for leaks.

If leaks are present, install a new steering damper.

Check torques on the following steering and suspension fasteners and adjust to specification as required (see following Table).

NOTE:

ADJUSTING TORQUE ON STEERING AND SUSPENSION FASTENERS IS VERY IMPORTANT IN RESOLVING THIS ISSUE. FASTENERS THAT ARE IMPROPERLY TORQUED WILL MAKE THIS ISSUE WORSE.

FRONT WHEEL ALIGNMENT AND REDUCE FRONT CASTER

NOTE:

OSCILLATION ISSUES RESOLVED BY WHEEL ALIGNMENT ARE WARRANTED FOR 12/12 ONLY, REGARDLESS OF OTHER STEPS PERFORMED.

Measure wheel alignment. Verify that Front Caster, Camber, and Total Toe are within specification. Adjust as required. Refer to the Workshop Manual, Section 204-00 for complete alignment specifications.

REDUCE FRONT CASTER

Note the current front caster

Use alignment adjustment bushings to reduce front caster by 0.5 to 0.75 degrees. The caster setting may be at the lower end of the specification as long as the vehicle drives smoothly. Do not put caster setting below the lower specification limit. Use alignment adjustment bushings

F-250/350 4X4:

5C3Z-3B440-CCC (0.5 degree bushing)

5C3Z-3B440-DDD (0.75 degree bushing)

5C3Z-3B440-EEE (1.0 degree bushing)

F-450/550 4X4 and 4X2:

5C3Z-3B440-HHH (0.5 degree bushing)

5C3Z-3B440-JJJ (0.75 degree bushing)

5C3Z-3B440-KKK (1.0 degree bushing)

F-250/350 4X2:

5C3Z-3B440-C (0.5 degree busing)

5C3Z-3B440-D (0.75 degree bushing)

5C3Z-3B440-E (1.0 degree bushing)

For All 4X4 and for F-450/550 4X2:

Rotate the alignment adjustment bushing so that the bushing hole is in the 45 degree forward and inboard position (See Figure 1)

Figure 1 – Article 06-22-14

This should lower the caster, while keeping the camber within the specification range. If the camber is not in the specification range than rotate the alignment adjustment bushing as needed

The final caster and camber settings must be within the specification limits

Maintain the current front camber, cross-camber and cross-caster settings as close as you possibly can

Adding weight behind the rear axle lowers the rear of the vehicle, which decreases the frame angle, which in effect increases caster

For All F-250/350 4X2:

Observe the camber position of the alignment bushing that is currently in the truck and attempt to maintain that position while moving the caster position forward in the truck

The final caster and camber settings must be within the specification limits

NOTE:

CASTER SETTING IS VERY IMPORTANT IN RESOLVING THIS ISSUE. INCREASING THE CASTER SETTING WILL MAKE THIS ISSUE WORSE.
